High Speed Positioning System

EPPDyL thrust stand was designed to accurately measure impulse bits of pulsed plasma thrusters (PPTs) within the range of 10-4-10Ns. It is theoretically predicted to be capable of measuring low steady state thrust, as low as 20µN. This project is in collaboration with the Electric Propulsion and Plasma Dynamics Lab at Princeton University (EPPDyL).

Experimentally determined during each measurement:

  • Instantaneous equilibrium position.
  • Effective spring constant.
